Nevertheless, it is during the last 10-15 years when fluid dynamics has become the standard tool to describe the evolution of matter created in ultrarelativistic heavy ion collisions. In this review I briefly describe the hydrodynamical models, what we have learned when analyzing the RHIC and LHC data using these models, and what the latest developments and challenges are.","authors_text":"Pasi Huovinen","cross_cats":["hep-ph","nucl-ex"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"nucl-th","submitted_at":"2013-11-08T00:04:09Z","title":"Hydrodynamics at RHIC and LHC: What have we learned?"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1311.1849","kind":"arxiv","version":2},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:6303b27b5c1a8f7464db082fb215b9b9b837d6c64f31f2e21ba3168ca450d252","target":"record","created_at":"2026-05-18T03:05:35Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"eb20f9fa43ab8085b3eae37d1d3a3dfa052b8efe4ae5450fc9a8ab798e496190","cross_cats_sorted":["hep-ph","nucl-ex"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"nucl-th","submitted_at":"2013-11-08T00:04:09Z","title_canon_sha256":"ede288fccd3a0008684d20020ffe6eb4e8d638fb03dc11f1098c7c9ca1c652cf"},"schema_version":"1.0","source":{"id":"1311.1849","kind":"arxiv","version":2}},"canonical_sha256":"b893c3a248165ef7acf200b90ce91e8059fa13816f666876fc06724da87918eb","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"b893c3a248165ef7acf200b90ce91e8059fa13816f666876fc06724da87918eb","first_computed_at":"2026-05-18T03:05:35.273948Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:05:35.273948Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"C3Ayx8BdZVpHqR79Vbnnjr6yIE4kEsBlJz6rNhIA9Cyt91jFyC2Jm0lNAjtkfQ36WRPgiBZ3nRvteZMJE3eIBA==","signature_status":"signed_v1","signed_at":"2026-05-18T03:05:35.274402Z","signed_message":"canonical_sha256_bytes"},"source_id":"1311.1849","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:6303b27b5c1a8f7464db082fb215b9b9b837d6c64f31f2e21ba3168ca450d252","sha256:4affb461b190cc68defb1471361f0b2c91af7839a68fb1e62a60641934d22928"],"state_sha256":"086217ca827f01d9f33f66d1cf218af421f90266a76f63dd5b53e062dcd6e418"}
